SubjectRe: Bios32.c and DK440LX

(Doug: I will cut you out of the CC list next round - I was not sure if
you needed to be in this ring - mgm)

I appreciate the attribute 8-) but Mingo actually wrote the patch for
Heikki's DK. She posted it to myself and I forwarded it on.

As far as the Ethernet thing - It happened between 117 -> 118. I suspect
that one of the IRQ simplifications ends up stripping out the high bits
(IE: XT style IRQ vs. AT) because the ethernet always was on IRQ 19
previously. And of course Mingo's patch is still in io_apic.c so on
DK440LX boards we end up sharing IRQ 9 between ethernet built-in and the
PIIX4 chip. This allows the DK to boot and load drivers but when you go to
open the ethernet card you get:

kernel: eth0: speedo_open() irq 9.
kernel: eth0: Done speedo_open(), status 00000090.

**** REBOOT (C-A-D) SYSTEM REBOOT WORKS ****
[snip of very good arguments]

I would agree here on the mapping issue. I have not had time to do more
that scan over the patch changes from 117 -> 118.

Mingo - If you would like the complete boot log for 120pre3 vs. 117 with
all the APIC details for my machine let me know. I was going to extract
some of the points of interest (similar to what Troy had posted about a
week ago WRT the PCI mapping lines changing) and post them but I am
heading off to Chicago on Tuesday (work...its a living) and won't have
time to dig in. Let me know and I can attach them to you. I will be back
the following week so if you would like me to test/sample/etc I can do so
then.
